What is the Doppler shift of galaxies?
It shows how galaxies are moving in relation to Earth.
What does red shift tell us about other galaxies?
Red shift indicates that other galaxies are moving away from us, implying that the universe is expanding. This phenomenon is a key piece of evidence supporting the Big Bang theory. The amount of red shift is used to determine the distance and speed at which other galaxies are moving relative to us.
Is the milky way galaxy growing with the universe too?
No, the growth of the universe is caused by the galaxies moving away from each other, with no relation to their size.
American astronomer Edwin Hubble later interpreted this discovery as evidence that?
Galaxies are moving away from each other in a constantly expanding universe.
What is it when galaxies move away at a speed proportional to their distance?
This phenomenon is known as Hubble's Law, which describes the relationship between the distance and the velocity at which galaxies are moving away from us. It is a key piece of evidence for the expansion of the universe.
In order to determine if an object is moving you must observe the object in relation to a?
In order to determine if an object is moving, you must observe the object in relation to a fixed reference point, such as another object that is not moving or the observer's own frame of reference. This comparison allows you to see if the object is changing position relative to the reference point, indicating movement.
How are galaxies moving today?
galaxies are movign further away from eachother
What is the significance of red shift galaxies?
It means they are moving away from us.
In which direction are nearby all galaxies moving relative to earth?
Nearly all galaxies are moving away from our galaxie and planet.
How many galaxies are approaching milky way galaxy and how many are moving away related to the cosmological red shift?
Most galaxies are moving away from us. Only a few galaxies, which are nearby, are moving towards us.
How do galaxies move?
they move by not moving.
Observation of the red shift of galaxies suggest that the universe is what?
Expanding. The red shift observed in galaxies indicates that they are moving away from us, and this phenomenon is a key piece of evidence for the expansion of the universe.
